Dual Thrust: Asymmetric Intraday Range Breakout
1. Introduction Dual Thrust is a classical intraday range breakout strategy developed by Michael Chalek in the 1980s, once ranked among the most profitable systems by Future Truth magazine. Its elegance lies in the minimal information requirement—only the previous day’s high, low, and close prices—and in the deliberate asymmetry embedded in its breakout thresholds. Unlike symmetric channel breakout systems (e.g., Donchian channels), Dual Thrust permits independent tuning of the upside and downside trigger distances, which introduces a directional bias that can be calibrated to the prevailing market regime. ...
